Subject: [PATCH] Workaround finding libudev on systems without ldconf

This patch tries to load libudev.so directly without relying on
Python's find_library(). find_library() fails on systems
without library cache mechanism.

Taken from pyudev issue 117 discussion:
https://github.com/pyudev/pyudev/pull/117
